An illegal move is completed once the opponent's clock has been started.
However, the opponent is entitled to claim a win before making his own
move. If the opponent cannot checkmate the player's King by any possible

is entitled to claim a draw before making his own move. Once the opponent
has made his own move, an illegal move cannot be corrected
